Installing the Fireplace
Step 1. Locating the Fireplace
The diagram below shows space and clearance require-
ments for locating a fireplace within a room.
THE FIRE-
PLACE MUST BE LOCATED FLUSH WITH THE OUTSIDE
OF AN EXTERIOR WALL!

Figure 2. Fireplace Dimensions and Locations
Clearance Requirements
The top and sides of the fireplace are defined by stand-offs.
The minimum clearance for the indoor side to a perpendicular
wall extending past the face of the fireplace is one inch (25
mm). The metal ends of the fireplace may
NOT
be recessed
into combustible construction.
WARNING: TO PREVENT CONTACT WITH
SAGGING OR LOOSE INSULATION, THE
FIREPLACE MUST NOT BE INSTALLED AGAINST
VAPOR BARRIERS OR EXPOSED INSULATION. LO-
CALIZED OVERHEATING COULD OCCUR AND A
FIRE COULD RESULT.
Step 2. Framing the Fireplace
Fireplace framing can be built before or after the fireplace is
set in place. Framing should be positioned to accommo-
date wall coverings and fireplace facing material. The dia-
gram below shows framing reference dimensions.
CAUTION: MEASURE FIREPLACE DIMENSIONS AND
VERIFY FRAMING METHODS AND WALL COVERING
DETAILS BEFORE FRAMING.
* The clearance to the ceiling is measured from the top
of the unit, excluding the standoffs (see Figure 9).
The distance from the unit to combustible construction is to
be measured from the unit outer wrap surface to the com-
bustible construction,
NOT
from the screw heads that se-
cure the unit together.
!
WARNING: FRAMING DIMENSIONS ASSUME
USE OF 1/2 INCH THICK WALL COVERING
MATERIALS ON EXTERIOR OF FRAMING ONLY AND
NO SHEETROCK ON INTERIOR OF FRAMING.

In cold northern climates pay attention to exposures and
prevailing wind conditions when locating the fireplace, the same
as you would for locating exterior windows and doors.
The Twilight has the thermal characteristics of a high quality
window system. Temperatures near the fireplace will be
cooler than what is realized with a fully insulated wall.
